Pages at the site often feature buttons that say "Add to Firefox".

Clicking on such a button causes a Firefox extension to be downloaded and installed.

I am looking for a convenient way to limit this action to the download step only, so that in the end I am left with the downloaded *.xpi file in my disk.


P.S. The following approach is not only inconvenient: it doesn't work!.

  1. Inspect the HTML for the button, and extract a URL like

    give or take the stuff after .xpi.

  2. at the command-line prompt, download this URL with wget or curl.

This download attempt just hangs. (Even if it didn't, I'd like to find a less cumbersome approach.)

Use a different web browser? – Zoredache Jun 25 '12 at 1:07

In Firefox, right-click on the download button and select "save link as" has always worked for me.

Go to the add-on you want to install and just right click on the +Add to Firefox button and select save link as. After downloading the file just go to File>Open File and just select the extension you have downloaded work like a charm for me.

Using another browser to download the plugin solves your problem.

Or you can just change the user-agent string and make your firefox look like another browser so you can download the extension.

But I know it isn't the best solution.
